Scientists have designed a robotic gripper that uses sound waves to move small and fragile objects, without touching them. The prototype robot developed by the researchers from ETH Zurich in Switzerland comprises of two semi-spheres, and resembles a pair of headphones.

The spheres are connected to a circuit board carrying microchips. A small sphere hovers between the two semi-spheres, held up by ultrasound waves.
